GM is predicted to sell a total of 50,000 cars with electrification technologies this year
General Motors is looking to take huge strides in the way of electric vehicles (EV) and electric batteries: it wants to produce 500,000 EVs per year, and it wants to use
Chevrolet Volt batteries
to power homes during blackouts.
According to GM, it wants to sell 500,000 vehicles equipped with its electric technologies (plug-ins, EVs, hybrids) annually by 2017. If GM is able to do this, EVs would make up 5.5 percent of its total annual sales.
This is a pretty big jump considering GM is predicted to sell a total of
50,000 cars with electrification technologies
GM is taking EVs very seriously, and is proving that by focusing on its next generation propulsion technology that is currently powering the Volt. GM is looking into new ways of using extended-range electric vehicle (EREV) technology.
Speaking of the Volt, GM is looking to use the EV's battery pack in an innovative way: powering homes in the event of an outage.
GM partnered with automation and power technologies company ABB Group as well as Duke Energy to find useful applications for EV batteries after they've been exhausted in vehicles.
The end result was a unit that contains five
Volt lithium-ion battery packs
that can provide two hours of electricity to three to five U.S. homes during a blackout. According to GM, the unit can provide 25 kilowatt hours of power and 50 kilowatt hours of energy.
"This is an industry first to be able to do secondary automotive batteries in a grid-based application," said Pablo Valencia, GM's senior manager of battery lifecycle management.
GM said the battery could last 10 years on the road and another 10 years as part of the power unit for blackouts.
Duke Energy is looking to install the unit in a North Carolina neighborhood for testing in 2013.

GM also talked up the ability to have the Volt power your home in a power outage situation. So does Ford.
Doesn't the Volt have a 15kw battery or something? That means it stores 15,000 watts of power. Since a refrigerator/freezer uses ~600 watts of power, that means you could run it for at least 27 hours non-stop (which refrigerators don't do, realistically you'd get at least a week out of it with moderate opening/closing.)
A full home uses about 10kw/day (the average annual electric bill is around 300kw/h a month according to my ComEd bill with a statistic from the EPA. So these cars in "generator" mode would power your home for at least 1.5 days if you continued using everything as if the power never went out. That's pretty good!

You can certainly cut back as well. A modern refrigerator uses a little over 1kWh per day, and another kWh for lights, microwave, cellphone, etc should let you get by almost a week on an EV battery in emergency circumstances.
